No need to check anything, it's described there:
http://skoe.de/kernal/kernal-cartridge.pdf

But be warned that this document is outdated and in
some details even wrong, thereas the basic principle is still the same.

Currently I'm cleaning up the VHDL implementation, when I've done this
I plan to release an updated CPLD core, to update that document and to
describe the actual implementation. The VHDL code and the hardware
design are all open and freely available, I'll post a link here as soon
as I have finished the refacturing - please don't look there at the
moment, it may be quite confusing to see code and comments which do/say
something completely different ;)
